It is an equilateral triangle so its angles are equal 60°. From the definition, we know that:
and
so
Answer:
A,B,C
Step-by-step explanation:
A-B is J so A would have the least
B-c is K so B would be the second
C-A is l so C would be the largest
Hope this helped
im not so familiar with this but try answering A
It should be A. Just factor 45
Answer:
Marry = $17
Ravi = $11
Alan = $34
Step-by-step explanation:
Let us assume
Mary be X
Ravi be Y
Alan be Z
So, the equation in total is
X + Y + Z = 62
It is given that
X = Y + 6
Z = 2X
Now we put the Z value in the total equation, so it would be
X + Y + 2X = 62
3X + Y = 62 .................................... (1)
And can we write
X = Y + 6
X - Y = 6 ................................. (2)
Now substitution these two equations,
3X + Y = 62
X - Y = 6
2X = 68
X = $17
So, Z = 2 × 17 = $34
And, Y
$17 + Y + $34 = $62
So, Y = $11
The area of trapezoid ABCD is
... Area = (1/2)·(BC +AD)·(BF)
We can fill in the given information and solve for the remaining variable.
... 30 = (1/2)(6 + AD)(4) = 12 + 2·AD
... 18 = 2·AD . . . . . subtract 12
... 9 = AD . . . . . . . divide by 2
Since AB || CE, the lengths BC and AE are equal; both are 6. So, we have
... AE + ED = AD
... ED = AD - AE = 9 - 6
... ED = 3 . . . . . corresponds to selection (A)
